George Washington Parke Custis

George Washington Parke Custis was the stepgrandson and adopted son of United States President George Washington, the grandson of Martha Washington and the fatherinlaw of American Confederate Army general Robert E. Lee. He spent part of his large inherited fortune constructing Arlington House on a plantation that was directly across the Potomac River from Washington, D.C. After Custis died, his daughter, Mary Anna Randolph Custis, who had married Robert E. Lee, inherited his estate.

George Washington Parke Custis was born on April 30, 1781, at his mothers family home at Mount Airy, a restored mansion now in Rosaryville State Park in Prince Georges County, Maryland. He initially lived with his parents John Parke Custis and Eleanor Calvert Custis, and his sisters Elizabeth Parke Custis, Martha Parke Custis and Nelly Custis, at Abingdon Plantation , which his father had purchased in 1778. However, six months after G.W.P. Custis was born, his father died of camp fever at Yorktown, shortly after the British army surrendered there.
